Selling a Michigan Duplex or Multifamily: Tax and Legal Special Considerations

Selling a Michigan duplex, triplex, or quadplex is not just selling two houses at once. The tax math splits differently depending on owner-occupancy, the financing pool is narrower, and the tenant compliance load multiplies with every unit.

The Owner-Occupied Duplex Tax Split

If you lived in one unit and rented the other, the sale gets allocated. The portion attributable to your principal residence may qualify for the Section 121 exclusion ($250,000 single / $500,000 MFJ). The rental portion is subject to depreciation recapture (25% federal Section 1250 rate) plus capital gains. Allocation is typically done by square footage.

Principal Residence Exemption (PRE)

Michigan’s PRE exempts the homestead portion from local school operating millage. On a duplex where you occupy one unit, you can typically claim PRE on your unit’s percentage of taxable value. The pure rental portion does not qualify.

Proposal A Uncapping at Sale

Michigan caps annual taxable value increases at 5% or inflation. When a duplex transfers, taxable value uncaps to State Equalized Value (50% of true cash value). For an investor pro forma, this means year-one property tax is often 30% to 80% higher than yours.

Financing Realities for 2-4 Unit Michigan Properties

Two to four unit residential properties are eligible for FHA owner-occupant financing (3.5% down) and conventional investor financing (typically 25% down). FHA appraisals flag chipping paint, missing handrails, and similar items.
